Overview

2017 UZ7 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2017 UZ7 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2017 UZ7 orbits the sun every 1,180 days (3.23 years), coming as close as 0.85 AU and reaching as far as 3.52 AU from the sun. Based on its brightness and the way it reflects light, 2017 UZ7 is probably between 0.127 to 0.284 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.

Close Approaches

2017 UZ7's orbit is 0.02 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.

2017 UZ7 has 1 close approaches predicted in the coming decades:
